What does IEC 61515 say?

IEC 61515 describes the requirements for simplex, duplex and triplex mineral insulated metal sheathed thermocouple cables and thermocouples: Type K, N, J, E and T. This standard does not apply to the product after it is being used. The most important requirements, which are used to make MI cable, are the ones that concern the dimensions with tolerances of the cable and the recommended operating temperatures in various combinations.
